You can use the following three types of comments in the program:

 

  • for one line: //
  • for one or few lines : { }
  • for one or few lines: (* *)

 

Example


program Test;
// this a single line comment. Everything that goes after double slashes 
// in this lines ignored
procedure Increment(var n: integer);
begin
{this is a multi line comment
in curly braces}
  n := n - 1;
end;
procedure Decrement(var n: integer);
begin
  n := n - 1; (* you can do *)
end;(*this as well*)
begin
  x := 100; // assign value
  Increment(x {this is an integer type variable});
  Decrement(x); (* decrease value *)
end.
